It is inorganic, colorless, odorless, non flammable, and non toxic. SF 6 has an octahedral geometry, consisting of six fluorine atoms attached to a central sulfur atom. It is a hypervalent molecule. Typical for a nonpolar gas, SF 6 is poorly soluble in water but quite soluble in nonpolar organic solvents. It has a density of 6.12 g/L at sea level conditions, considerably higher than the density of air (1.225 g/L). It is generally transported as a liquefied compressed gas. The concentration of SF 6 in Earth's troposphere reached 10 parts per trillion (ppt) in year 2019, rising at 0.35 ppt/year. The increase over the prior 40 years was driven in large part by the expanding electric power sector, including fugitive emissions from banks of SF 6 gas contained in its medium and high voltage switchgear. Uses in magnesium, aluminum, and electronics manufacturing also hastened atmospheric growth.

2013/12/10The drawing shows why the arcing fault current I a is considerably less than the bolted fault current I bf in low voltage equipment, while it is about 90% of I bf in medium voltage and high voltage equipment. This is because the arc voltage drop, which is approximately 200 V for a 2 in. arc, is a significant part of the circuit voltage in 480 V

2004/1/1Testing the integrity of insulation requires measuring its resistance to current flow across it. A high level of resistance means that very little current is escaping through the insulation. Conversely, a low level of resistance indicates a significant amount of current may be leaking through and along the insulation.

hv Purity manufacturer
Abstract Plastics that are used for the insulation of medium, high and extra high voltage cables have to comply with the highest purity standards. Most commonly XLPE (cross linkable polyethylene) material is used for the insulation of cable. For cross linking of the XLPE the cable passes through a CV tube (continuous vulcanization tube) where it is exposed to high temperatures for the cross
